An important thing to remember is that Dwarf mutation CANNOT pass without a Lion Scrotum!
So she only has a chance to pass Dwarf mutie is she had a Lion Scrotum used - without it her chance to have a dwarf cub is the same of any non-mutated lioness!

Only Lion Scrotum matters with dwarf breedings; fertility, and other mutation increasing items such as GMO cow DO NOT affect her chances to have a dwarf cub, no more than they would affect any random non-mutated NCL! So you dont need to care about her fertility when breeding her; it only affects her chance to birth a random achromia or folded ears but in NO way affects her chances to birth a Dwarf! Only Lion Scrotum matters in Dwarf passing!

That said, it was simply an unlucky litter then if you didnt get any dwarves from your Lion Scrotum! If it was "overridden" by anything, then you would have achromia/adult mutation present/etc. other mutation cubs - if its just not mutated cubs, then it's just a failed roll.

You cannot use both on a single breeding as they take same breeding item slot; so you would need to sell the GMO cow and get a lion scrotum, otherwise breeding your dwarf will be the same as breeding any random NCL with a GMO cow. GMO cow only increases chance of random mutations - achromias, folded ears, bobbed tails, etc... it does no good for dwarf breeding, as it does not at all consider the mother's mutation. Lion Scrotum is the only item that works for a chance to pass dwarf's mutation.

The official mutation roll order: Pon/OG Fur/Gon > Patches/Pie > GMO Cow/Lion Meat > CRB > Fertility > Lion Scrotum > Primal > Mukombero

This does not mean that fertility chance necessarily overrides Lion Scrotum, though, it just rolls before it.

Oh thankyou this makes more sense, does this mean in a way my mutation chance is slightly boosted?

so i accidentally bought a GMO Cow instead of a lion scrot because i got mixed up somewhere and didn't think that it would matter when breeding came but after reading this it sounds like it matters. this is my very very first time breeding dwarves, would it be best to re-sell the GMOs (same price i bought them ofc) and buy lion scrot, use jus the GMOs, or buy a lion scrot and use both?

this is what i had in mind on applying items: breed>crb>gmo/scrot>breed>ibf

If there's any other/better items i should use please lmk how and when and what their use is, I want my chances for a dwarf to be the highest possible <3

so i should do scrot>breed>ibf? right?

Correct; preferably also use a Buffalo Scrotum when Breed so you have a chance at more cubs, Lion Scrotum is run per cub so more cubs in a litter increases chances for it to work. But even with both scrotums used, it may still fail and birth no dwarves, its important to remember there's no guarantee.

for sure! I already have my buff scrot, that's used on the male/stud right?

Correct! Buffy on the male, Lion Scrotum on the female, and breed them. Good luck!
